RAILWAY CAR.

Application filed April 24, 1923. Serial No. 634,233.

To all whom t may concern.'

Be it known that l, EMIL Ersnrfr, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful lmprovements in Railway Cars; and l do hereby declare the following to be a full, clear, and exact descriptin of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to railway cars and more particularly to improvements in selfpropelled railway cars in which the motor is a gas engine of the explosive type.

The principal object of my invention, generally considered, is to provide a simple, efficient and economical self-propelled railway car which can be advantageously employed as a switching engine in yards or manufacturing plants to expeditiously handle freight cars and to move the same from point to point as desired.

Another object of the invention is to provide a railway car having an underframe to which are rotatably connected axles having the usual flanged wheels fastened thereto to adapt the same for the standard gage track, the said underframe being so arranged and adapted as to permit the ready attachment thereto and detachment therefrom of a supplemental frame, the said supplemental frame including, as a self-contained unit, a gas engine of the explosive type, a variable speed transmission mechanism, a clutch mechanism, and a driven shaft, the driven shaft being provided with means for connecting the same to at least one of the axles journaled upon the underframe.

Still another object of the invention is to provide, in combination with an underframe having suitable supports, a gas engine tractor of a well known type, said tractor being adapted to be detachably connected to said supports, said tractor being so arranged that the driven shaft or axle thereof is operatively connected to an axle carried by said underframe'.

There are other objects of the invention as will hereinafter bemore fully pointed out in ecnnection with descripticn of the single embodiment of the invention which has been illustrated on the accompanying drawings in which:

Figure 1 is a side elevation of a railway car embodying the invention.

Figure 2 is atop plan view of the construction shown in Figure 1, portions being omitted for the sake of clearness.

Figure 3 is a front elevation of the construction shown in Figure 1.

Figure 4 is a fragmentary detail view taken substantially on the line 4-4 of Figure 2.

Figure 5 is a side elevation of a portion of the underframe adjacent the front axle thereof.

Figure 6 is a transverse section through the underframe taken substantially on the line 6-6 of Figure 5.

Figure 7 is a sectional view taken on the line 7--7 of Figure 6.

rlhroughout the various figures of the drawings like parts are designated by like reference characters.

ln the drawings the numeral 1 designates an underframe comprising side members 2 2 and end members 3 3, the side members preferably comprising built-up I-beams although it will be understood that the usual rolled lf-beams may be substituted therefor if desired. At opposite ends of the underframe 1, there are provided sub-sills 4, preferably in the form of -beams, and depending from the forward pair of sub-sills 4, as most clearly shown in Figure 5, are angle brackets 5 to which is detachably connected, by means of the bolts 6, a cross member 7.

The underframe is provided at opposite ends with rigid axles 8 which are journaled in bearings provided on the sub-sills 4. At points adjacent the rear axle 8 there are provided housings 9 which preferably comprise upper and lower members 10 and 11, respectively, said members being detachably connected by means of the bolts and nuts 12.

At opposite ends the side and end members of the underframe 2 and 3, respectively, are connected by means of cover plates 13 and depending from the lower portions of the side members 2 at opposite ends of the car are brackets 14 which, in connection with the angle bars 15, and the transverse plates 16, form stop plates at opposite ends of the underframe. Passing through suitai ble openings in the end plates 3 and arranged on the longitudinal center of the car or underframe are the usual couplers 17, and supported in any suitable manner upon the plates 13 is the uncoupling mechanism 18. Also connected to the opposite ends of the car underframe in any suitable manner are hand rails or grip bars 18a.

The power unit 19 comprises the well known Fordson kerosene tractor frame having as a self-contained unit an engine 20, a variable speed transmission mechanism 2'1, a universal and axle or shaft housing 22, and a driven shaft 23. At its forward end the tractor frame or supplemental frame is provided with a pair of ears 24 which are adapted to straddle the cross member 7 hereinbefore described and to which the same are connected by means of a bolt or other suitable fastening 25. Adjacent the opposite end the housing 22 is adapted to fit within theopening within the housings 9 and is rigidly connected to the side members of the underframe by means of the blocks 10 and 11 and the bolts 12. It will be readily observed that this supplemental frame forms a rigid cross member connecting the side member 2 of the underframe at points adjacent the rear axle and reinforces the underframe materially. It will be also noted that the supplemental or tractor frame is readily atc tachableto and detachable from the underframe, as desired.

To the outer ends of the shaft 23 are con- Vnectedgear wheels 26 preferably by means of the keys 27 shown most clearly in Figure 4. rIhese gear wheels 26 are adapted to intermesh with correspondingly formed gears 28 which are carried by the rear axle 8 and which are rigidly keyed thereto.

At the outer ends of the axles 8 I provide flanged wheels 29 and correspondinr wheels on each side of the underframe are preferably connectedby the connecting rods 30, as

Y `As illustrated in the drawings, the motor unit comprises a lradio 36 having the usual filling opening 37, a fuel supply tank 38, a carbureter 39, and an intake manifold 40, and to. control the variable speed transiaeaose mission there is the usual gear shift lever 41 and the clutch pedal 42.V

Having now described the invention, what I claim and desire to secure by Letters Inatent, is:

1. In a railway car, the combination with the underframe having axles connected thereto, of a Fordson tractor frame detachably` connected to` said underframe, said frame including a gas engine of the explosive type, a transmission mechanism and a power transmitting shaft arranged transversely of said car, and means for operatively connecting said shaft to at least one of said axles.

2. In a railway car, the combination with the underframe having axles rotatably connected therewith, wheels ,rigidly connected to said axles, of a Fordson tractor frame connected to said underframe at a plurality of spaced points` said frame including a gas engine of the explosive type, a variable speed transmission and a power transmitting shaft arranged parallel to said axle, and means for connecting said shaft to one of said axles.
